SILO CONSTRUCTION.

To all whom it may concern:

Be it known that We, CHARLES S. FINZER, HOMER F. FINZER, EDWARD G.FINZER, and WILLIAM D. FINZER, citizens of the United States, residingat Sugarcreek, in the county of Tuscarawas and State of Ohio, haveinvented certain new and useful Improvements in Silo Construction, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to new and useful improvements in theconstruction of silos and more particularly to the form of material ofwhich the silo is to be constructed and the main object of the presentinventlon is the construction of a silo by a new and novel formof-building block wherein to prevent the ensilage from freezing duringthe coldest period of winter.

Another object of the invention is the provision of novel constructionof building block which provides suitable air spaces between the innerand outer Walls of the silo and also to provide means for securelyretaining the blocks in position after the silo has been constructed.

A further object of the present invention is the provision of a silo ofthe above character which will possess advantages in points ofefficiency and durability, is inexpensive to manufacture an d at thesame time is simple in construction and operation.

\Vith the above and other objects in view, the invention consists in thenovel features of construction and the combination and arrangement ofparts to be hereinafter more fully described, pointed out in the claimand shown in the accompanying drawings, in which Figure 1 is a frontelevation of a silo constructed in accordance with our invention, partsthereof being broken away and shown in section; Fig. 2 is a detailelevation of a portion of the front part of the silo taken from theinner side looking out through the entrance and showing part of thedoors in position; Fig. 3 is an enlarged detail side eleva'tion, partsbeing broken away and in section at one side of the doorway; Fig. 4 is aSpecification of Letters Patent.

transverse enlarged sectional view through one form of the blocksillustrating the other form in elevation; Fig. 5 is an elevation of oneside of the doorway, parts thereof being broken away and in section;Fig. 6 is a transverse sectional view of one of the block formsillustrating the construction of the blocks which are laid next to thedoorway; Fig. 7 is a detail end elevation of one of the chamber form ofblocks illustrating the construction of the blocks which are arrangedadjacent the doorway.

; Referring more particularly to the drawings, 1 indicates the base ofour improved silo which is formedby providing an annular ditch in theearth and filling the same with a form of concrete, thus providing anannular supporting portion, as shown at 1, forming a foundation for thesilo. The bottom of the silo which is preferably circular in form andindicated by the numeral 2 is formed of a concrete material similar tothat of the foundation 1 and is arranged within the annular ring of thefoundation, as clearly illustrated in Fig. 1.

In the construction of our improved silo, we employ two forms ofbuilding blocks,

one form of which is clearly illustrated in cross section in Fig. 6, thebody 3 of which is preferably substantially rectangular in cross sectionand of hollow form. These blocks, when arranged in position are placedupon their ends and arranged in vertical parallel relation in a circleto coincide with the form of the body of the silo. This form of block isprovided upon its longitudinal side portions with the verticaldove-tailed grooves 4 which when the blocks are arranged in position andthe mortar placed between the same will receive the mortar and thusprovide an adhering surface so that the mortar placed between the blockswill more readily stick to them than if a smooth surface was provided.In each of the blocks which are indicated by the numeral 3, the numeral5 indicates the inner face thereof, and the inner. face of each of saidblocks which are arranged adjacent the doorway 6 are provided with anoffset portion 7 forming a suitable shoulder 8 upon which is arranged astrip of felt 9 against which the edges of the door 16 are adapted toabut.

side of the body of the silo, asclearly illustrated in Fig. l.

The other formof block which is used in constructing our improved silo,is clearly illustrated in Figs. 3 and 4. This form is substantiallyrectangular and is provided upon its interior with the spaced partitions10 which form air spaces, the outside of one of said air spaces beingindicated by the numeral 11 and the two inside air spaces beingindicated by the numeral 12. The form of block illustrated in Figs. 3and 4 are preferably laid upon their side edges when in position and thelayers, alternately arranged between the layers of the blocks indicatedby the numeral 3. Thus when the blocks 9 are arranged in position, theupper edge of the chamber 11 will be open while the chambers 12 will bepreferably closed to provide suitable air chambers.

After the blocks 9 have been laid in position, the chambers 11 which arearranged upon the outer side of the body of the silo are preferablyfilled with cement or any form of concrete, as shown at 13, and arrangedwithin this open chamber and inclosed by the cement is a metal band 14which encircles the body of the silo and materially assists in retainingthe blocks in position. Mounted upon the band 1d at the point where thesame crosses the door open-- ing '6 is a casing 15, the ends of whichare embedded within the concrete 13 so as to securely hold the casingsin position. The blocks 9 which are arranged adjacent the door openin 6are provided with the 0&- sets 7 whic are adapted to be arranged inalinement with the offsets 7 so that the shoulders 8 which are formed bythe ofl'sets 7 will be arranged in alinem'ent with the ofisets 8 and thestrip of felt Will engage over both of the ofisets.

The door members which are generally indicated by the numeral 16 aresecurely held in position by means of the bolts 17, the inner ends ofwhich are provided with an enlarged circular head 18 and adapted to becountersunk within the front face of the door and arran ed behind theplate 19 which is secured to t e door, thus retaining the bolt inposition. The outer end of the bolt 17 is threaded andmounted thereon isa U-shaped member 20 which is adapted to engage over the casing 15mounted upon the band let as it crosses the doorway and a nut 21 retainsthe U-shaped member in position so that the doors will be securely heldin place until the bolt 17 is removed. The roof The doorway of the silowhich is' indicated by the numeral 6 is formed at one miaaoe of the silowhich is generally indicated by the numeral 22 is securely retained inposi- The roof of the silo is supported upon the beams 26 which may besecured in any suitable manner to the annular plate 24.

From the above description taken in connection with the accompanyingdrawings, it will be readily apparent that we have pro vided a simpleand durable silo, the construction of which will prevent the ensilagefrom freezin during the cold Winter months and a so to provide a novelmeans for retaining the concrete blocks, of which the body of the silois constructed, in position so that they willnot be forced out ofposition by the swelling of the ensilage and the weight of the ensilagewhich bears against these blocks. The outer face of the blocks adjacenteach side of the door opening 6 are provided with suitable openings 26in which bolts or other fastening means are to be arranged in securing achute to the silo when removing the ensilage or placing the sametherein. It will be understood that the bolts which are arranged withinthese openings can be quickly and readily removed when desired so thatthe chute may be placed in various desired positions. From the abovedescription, it will be readily apparent that we have provided a simpleand durable silo which can be quickly and readily set up in position andwhich at the same time can be manufactured and placed upon the market atcomparatively small cost.

While we have shown and described the preferred form of our invention,it will be obvious that various changes in the details of constructionand in the proportions may be resorted to for successfully carryin ourinvention into practice without sacricing any of the novel features ordeparting from the scope of the appended claim.

What we claim is i The combination with a silo wall including'circularbands embracing portions of said wall, said wall being provided with avertical door opening, removable doors arranged therein, and said bandsextending across the door opening, of casings mounted upon said bandswithin the door opening, bolts having their head portions embeddedwithin the outer face of the doors, means applied to the doors to retainsaid head portions in position, U-shaped members mounted upon thethreaded ends of the bolts, and our signatures in the presence of twowit- 1o embracing the casings, the ends of said nesses.
